The Dark Rift – Book One – The Last Artifact Trilogy by Gilliam Ness

THE MYSTERY OF MYSTERIES…
BETWEEN TRUTH AND MYTH…
BETWEEN DARKNESS AND LIGHT…
WILL BE REVEALED.

250 million years ago an extinction level event wiped out 98% of life on earth.
Nobody suspected it was cyclical until now.
The countdown to a great leap forward in human evolution has begun, but history has a way of repeating itself, and it could easily mean the end of all things.

When they come into possession of a mysterious prehistoric cube, relic hunter Gabriel Parker, and the alluring artifact historian Natasha Rossi, find themselves inexplicably bound to a dark mythology dating back to the roots of civilization.
